SPECIFICATION forming part of Letters Patent No. 768,433, dated August23 1904. Application filed April '7, 1904:. Serial No. 202,032, (Nomodel.)

To all whom it may concern: 7 I

Be it known that We, T OMAS EAsTMooRn and MATHEW M. FREED, both citizensof the United States, and residents of Jacksonville, in the countyofDuval and State of Florida, have invented a new and Improved Turbine,of which the following is a full, clear, and exact description. 4 v IThis invention relates to improvements in multiple compound expansionsteam-turbines,

an object being to provide a machine of' this character that will beeffective in operation, simple and durable in construction, easilyreversed, and arranged to utilize the motive agent to the fullestextent. We will describe'aturbine embodying our invention and then pointout the novel features in the appended claims.

Reference is to be had to theaccompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a top plan view, with parts broken away, of aturbineembodying our in vention. Fig. 2 is a sectionon the line at w ofFig. 3, and Fig. 3 is a longitudinal vertical section. V

The turbine co'mprises a cylinder 1, divided into a plurality ofchambers A B G by means of partitions 2 and the cylinder heads 3. Thesepartitions .2 may be secured in place by any suitable means. We havehere shown the partitlons as secured in placeby means of bolts 4:.Extended through the cylinder-headsand also through the partitions is apowershaft 5, which has bearingsinboxes 6, secured to the heads, theseboxes having interior channels to receive packing-rings 7 of gun-metalor the like, and. these rings also engage-in channels formed in theshaft;

similar construction, and each comprises an inner rim 11 and an outerrim 12, and between mounted in bearings on the cylinder.

Oil-cups 8, mounted on the bearing-boxes, have commu- ;the inner andouter rims are spirally-disposed flanges 13, which form the walls ofbuckets 'or pockets in the wheels. The inner rims 11 are providedwithpacking-rings 14:, forced outward by means of springs 15, and theouter rims v12 are provided with similar pack' ing-i-ings l6, forcedoutward by springs 17.

The partitions 2 are provided at the upper side with ports 18 19, theopenings of which are governed by plug-valves 20, having screwthreadengagement in socket members 21 on the cylinder, and the outerj ends ofthe valves are provided with hand-wheels 22. Near the,

lower sidethe partitions are provided with ports 23 24:, in which valves25 operate similar tothe valves 20. It will be noted that the port 19 issomewhat larger in area than the port 18, so as to permit of the passageof expanded. steam readily from the chamber A to the chamber B and fromsaid chamber B tothechamber C when the turbine is rotating in onedirection. The lower ports are :reversely arrangedthat is, the port 23is somewhat larger than the'port 2 1 to permit 1 the passage of theexpanded steamwhen the Wheel is rotating in the reverse direction.

The chamber A has an inlet 26 for live steam, which is controlled by avalve 27 in the valve-casing 28, and at the lower portion the saidchamber A has an exhaust port 29, controlled by a Valve 30, on the stemof which is an arm 31, connected to a link 32, the upper end of saidlink being pivotally engaged with an arm 38,.extended from the stem ofthe valve 27 and also on the stem of said valve is an upwardly-disposedarm 34, which con- 'nects with an arm 35,projected from a shaft 36,

7 At the opposite end the chamber Chas an inlet-port 37, controlled by avalve 88, and an exhaustport 39, controlled by a valve 10. Connected tothe stem of the valve 38 is an arm ll, from which a link 42 extends to aconnection with an arm 13 on the stem of the valve 10, and also on thisstem is an arm 1 1, connected, by means of a link 15, with an arm 4:6 ona shaft 17, mounted to rock in bearings on the cylinder. It will benoted that the arm 34 is connected to the arm 35 through themedium of alink 48, similar to the link 45. From an arm 49 on the shaft 36 adraw-rod 50 extends to pivotal connection with a reversing-lever 51, andfrom this reversing-lever 51 a draw-rod 52 extends to a connection withan arm 53 on theshaft 4'7. The shifting lever 51 is provided With aspring-pressed pawl M for engaging with any one of the teeth in asegment-rack 55, so as to hold the valves as adjusted to permit theentrance and exhaust of more or less steam. By this valve-actuatingmechanism it is obvious that the direction of rotation of the turbinemay be quickly reversed.

As the parts are indicated in Fig. 3, the actuating medium is admittedthrough the port 37 and passes into the chamber C to operate upon theWheel-section in said chamber, and thence the slightly-expanded steampasses through the port 24 to operate upon the Wheel in the chamber B,and thence the expanded steam passes into the chamber A, actuatingmounted on the shaft within the chambers,

each Wheel-section comprising an inner rim and an outer rim,spirally-disposed flanges arranged between the inner and outer rims, andports .in the heads and partitions for directing steam through theseveral chambers.

2. A turbine comprising a cylinder, partitions arranged in the cylinder,headers for the cylinder, the said headers and partitions forming Wallsof chambers in the cylinder, a shaft extended through the headers andthrough the partitions, turbine-wheel sections mounted on the shaft inthe chambers, valvecontrolled inlet and outlet ports in the headers,valve-controlled ports leading through the partitions, and means forsimultaneously operating the valves in the first-named ports.

3. A turbine comprising a cylinder, headers for the cylinder, partitionsarranged in the cylinder and having ports, the said headers also havingports, screw-valves for controlling the ports in the partitions,plug-valws for controlling the ports in the headers, and means forsimultaneously reversing the several plugval\ 'es.

4. A turbine con'iprising a cylinder, a shaft extended through thecylinder, a turbinewheel mounted on the shaft and divided into aplurality of sections, an exhaust-port leading through each header, aninlet-port leading through each header, valves for controlling theports, link connections between the valves at each end of the cylinder,rock-shafts supported on the cylinder at each end, arms extended fromthe rock-shafts, link connections between said arms and theinlet-controlling valve at one end and the exhaust-controlling valve atthe other end, a reversinglever, and rods connecting saidreversing-lever with said shafts.

5. A turbine comprising a cylinder, heads for the cylinder provided withinlet and outlet ports, partitions arranged in the cylinder and havingvalve-controlled ports, a shaft extending through the cylinder-heads andpartitions, turbine-wheel sections mounted on the shaft, valves forcontrolling the inlet and outlet ports in the cylinder-heads, and meansfor simultaneously reversing the said valves.

6. A turbine comprising a cylinder having heads and partitions dividingthe cylinder into a plurality of chambers, a shaft extending through thecylinder, turbine-wheel sections mounted on the shaft within thechambers, each of said wheel-sections comprising an inner rim, an outerrim and spirally-disposed flanges arranged between the rims, each ofsaid partitions being provided with valve-controlled ports located nearthe top and bottom of the partition, respectively, and connecting theadjacent chambers, the end chambers of the cylinder each having an inletand an exhaust port, valves controlling the said inlet and exhaustports, a reversing-lever, and connecting means between the said leverand the severalinlet and exhaust values for simultaneously reversing thesame.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
